wrong cyclic for record structure

[Vitalij Ruge]

For the following model

package cyclic
  record rec
    parameter Real a;
    parameter Real b;
  end rec;

  model m
    parameter rec A(a = B.a, b = 1);
    parameter rec B(a = -1, b = A.b);
  end m;
end cyclic;

we find a cycles for m.

expect flattering without cycles:

  model m
    parameter Real B.a = -1;
    parameter Real A.a = B.a;
    parameter Real A.b = 1;
    parameter Real B.b = A.b;
  end m;

Works fine in the new frontend.
